What is what does x mean in texting from a guy?

As an AI language model, I cannot predict the intention of a person's text. However, "x" in texting from a guy can mean different things depending on the context and the sender's relationship with the receiver. Generally, "x" is used as a substitute for a kiss. It can either indicate a friendly gesture, or it may represent romantic interest. Additionally, x can also represent an abbreviation for "ex" or "unknown" in some contexts.
